Sulfur degasser apparatus and method

摘要

A novel system and method for degassing H2S and H2Sx from liquid sulfur (sulphur) is disclosed. The system includes a degassing vessel with a plurality of cells. The cells include a sparging gas mat with a perforated surface at the bottom of the cell to allow the release of air bubbles (or sparging gas) into the cells. A catalyst may be used during the process. As a result, hydrogen sulfide and hydrogen polysulfide are efficiently and effectively removed from the liquid sulfur.

1. A sulfur degassing apparatus for removing hydrogen sulfide and hydrogen polysulfide from liquid sulfur, comprising:
a vessel containing the liquid sulfur; said vessel comprising a cell and a sparging gas mat disposed within the cell, wherein said sparging gas mat includes a perforated plate for releasing a sparging gas into the cell and internal partitions attached to the perforated plate and creating a plurality of compartments below the perforated plate, wherein a plurality of openings in a sparging gas pipe provide for sparging gas to flow into the plurality of compartments, and wherein said sparging as mat includes a frame and internal partitions attached to the frame and to the perforated plate to form the plurality of compartments.
